When installing

pip3 instal pyopenssl

Mistake:

Command python setup.py in / tmp / pip-build-mycc1h6w / cffi Storing debug log in / tmp / pip-build-mycc1h6w

Last lines of the log

 Dezmont@137407:~$ /usr/bin/python3 -c 'import OpenSSL' Traceback (most recent call last): File "<string>", line 1, in <module> File "/usr/local/lib/python3.4/dist-packages/OpenSSL/__init__.py", line 8, in <module> from OpenSSL import rand, crypto, SSL File "/usr/local/lib/python3.4/dist-packages/OpenSSL/SSL.py", line 112, in <module> if _lib.Cryptography_HAS_SSL_ST: AttributeError: 'FFILibrary' object has no attribute 'Cryptography_HAS_SSL_ST'

How to solve this problem?

  • tried sudo apt-get install python3-openssl ? - jfs
  • Tried did not help - Dezmont
  • What does "not help" mean? What does dpkg -l python3-openssl show? What error: /usr/bin/python3 -c OpenSSL ? - jfs
  • @jfs is something like this when installing cryptography is also a mistake, but different. You can see for yourself, I will give the password. But I already broke my whole head - Dezmont
  • python3 -с OpenSSL is my mistake. I meant: /usr/bin/python3 -c 'import OpenSSL' . (don't forget /usr/bin/ ) - jfs

I solved the problem by removing the old version of pip

 sudo apt-get remove --purge python-pip sudo rm -rf /usr/local/lib/python2.7/{dist,site}-packages/pip* sudo rm -rf /usr/local/lib/python2.7/{dist,site}-packages/pillow*

The answer here found

  • The commands that try to remove a broken pip installation for Python 2 have nothing to do with installing the package in Python 3 . - jfs
  • @jfs May not have. But everything finally worked, and this is important - Dezmont
